What errors can there be in this go code that it doesn't run?

Question

go

The code does not compile, i.e. exe file is missing. When you try to run it in the online editor on the go site, the first line is displayed, but then it says program exited. With what it can be connected?

package main
import (
  "fmt"
)
func main(){
  //declarating variables
  var objecttype int
  var mass int
  var length int
  var width int
  var hight int
  var density int
  var subjecttype int
  var liquidtype int
  //var viscosity int
  //var thermalconductivity int
  var amount int

  //
  fmt.Printf("Hello, please, carefully read instructions.")
        fmt.Printf("Now please choose a type of the object, material subject (like a cube), or electric (like a transistor). Just enter 1 or 2.")
  fmt.Scan(&objecttype)
  //For object
  if objecttype == 1{  //object
    fmt.Printf("Please enter subject length")
    fmt.Scan(&length)
    fmt.Printf("Please enter subject width")
    fmt.Scan(&width)
    fmt.Printf("Please enter subject hight")
    fmt.Scan(&hight)
    fmt.Printf("Please, enter the mass of the subject")
    fmt.Scan(&mass)
    fmt.Printf("Please, enter the density of the subject")
    fmt.Scan(&density)
    fmt.Printf("Please, choose subject type: liquid, metal, non-metal, just type 1, 2 or 3")
    fmt.Scan(&subjecttype)
    //for liquid
    if subjecttype == 1{
      fmt.Printf("Please, select one of existing liquids:")
      fmt.Printf("1 - Mercury")
      fmt.Printf("2 - Glycerol")
      fmt.Printf("3 - Milk")
      fmt.Printf("4 - Sea water")
      fmt.Printf("5 - Water")
      fmt.Printf("6 - Sunflower oil")
      fmt.Printf("7 - Oil")
      fmt.Printf("8 - Alcohol / Ethanol, kerosene")
      fmt.Printf("9 - Petrol")
      fmt.Printf("If your liquid not declared here, type 0")
      fmt.Scan(&liquidtype)
      if liquidtype == 1{
        density = 13600
        //viscosity = 1 //0.001526
        //thermalconductivity = 1 //8.3
        fmt.Printf("Please, enter the mass of the mercury")
        fmt.Scan(&mass)
        fmt.Printf("Please, enter the amount of mercury")
        fmt.Scan(&amount)
      }

    }
  }
}

How are you trying to compile it?
Just compiled under Ubuntu - everything is ok.
